+ make DESTDIR=/var/tmp/assuma-3.0-build install
make: Nothing to be done for `install'.

How can i define the place who are must installed the files?

There's no install target defined in the Makefile - according to the
README it's on purpose:
"Since this version is an beta version their no such thing as "install"...".
Simply copy the "association_subscribers_manager" binary into your buildroot.
